Aug 18 03:04:35 <kremlin> hello -- is there any way to check the frequency of the master oscilator on the BBB? the crystal that is at 19.2MHz/25MHz/26MHz
Aug 18 03:09:02 <zmatt> it's 24 MHz
Aug 18 03:09:57 <kremlin> zmatt: how can you be certain?
Aug 18 03:10:05 <zmatt> component Y2 in grid cell D5 of page 3 of the schematic
Aug 18 03:10:44 <kremlin> aha, it's a BBB thing, not an am335x thing
Aug 18 03:11:12 <zmatt> well the board uses strapping options to indicate which of the four choices is used
Aug 18 03:11:35 <zmatt> bootrom performs initial PLL configuration based on that
Aug 18 03:11:57 <kremlin> gotcha
Aug 18 03:12:13 <kremlin> so the bootrom decides, and it always decides 24MHz?
Aug 18 03:12:37 <zmatt> well ultimately the crystal used is what decides the master clock
Aug 18 03:13:23 <zmatt> rom however doesn't attempt to somehow auto-detect its speed, it needs to be told via the sysboot14-15 pins
Aug 18 03:14:05 <zmatt> which have pull-up/down resistors on the board
Aug 18 03:14:18 <kremlin> i see
Aug 18 03:14:36 <zmatt> since the bbb has a 24 MHz crystal, it has a pulldown on sysboot15 and pullup on sysboot14
Aug 18 03:16:02 <zmatt> if rom is misinformed then as a consequence it would misconfigure the PLLs, which means anything timing-sensitive (usb, ethernet, video, uart) will not work correctly or at all, and you may end up overclocking the am335x
Aug 18 03:17:20 <zmatt> (u-boot and linux, if you manage to get that far, would likewise use the wrong information for setting up clocks)
Aug 18 03:19:53 <kremlin> i see
Aug 18 03:21:52 <kremlin> okay, now i can trust the clock tree tool
Aug 18 03:21:53 <kremlin> sort of.
Aug 18 03:23:33 <zmatt> note that rom and u-boot combined already do pretty much all clock setup you need unless probably
Aug 18 03:24:18 <kremlin> this is for the LCD controller
Aug 18 03:24:20 <zmatt> so there's probably not that urgent a need to meddle with it in eh... freebsd was it? openbsd? netbsd? somebsd
Aug 18 03:24:23 <zmatt> ah
Aug 18 03:24:25 <zmatt> right
Aug 18 03:24:49 <kremlin> openbsd :)
Aug 18 03:25:09 <zmatt> ah well, second guess, close enough
Aug 18 03:25:48 <zmatt> at least I remembered it wasn't plan9
Aug 18 03:26:05 <kremlin> interesting you mention that...
Aug 18 03:26:14 <kremlin> i work on plan 9 in my spare-spare time
Aug 18 03:26:38 <zmatt> plan9 is very likeable
Aug 18 03:26:44 <zmatt> abstractly
Aug 18 03:26:51 <kremlin> it's my absolute favorite software bar none
Aug 18 03:27:10 <kremlin> it's the only operating system ever written that isn't unix
Aug 18 03:27:26 <zmatt> that's a biiit of an overstatement
Aug 18 03:27:44 <kremlin> i don't think so
Aug 18 03:28:08 * zmatt was raised a mac user :P
Aug 18 03:28:20 <zmatt> except it stopped being mac with osx, then it became a crappy unix system
Aug 18 03:28:29 <Rickta59> if they only had better graphics it might have been popular
Aug 18 03:28:50 <kremlin> macOS was before my time, however, iirc mach was based on 4.4BSD
Aug 18 03:28:53 <kremlin> good ol reno
Aug 18 03:28:56 <kremlin> (also way before my time)
Aug 18 03:29:02 <zmatt> well there are still people keeping mac os 9 alive, they already share the 9 so maybe they should get married ;)
Aug 18 03:29:10 <zmatt> j/k
Aug 18 03:29:18 <kremlin> hehe
Aug 18 03:29:47 <zmatt> macos may have been before your time, that doesn't mean you can make statements about what was "ever written" :P
Aug 18 03:30:07 <kremlin> fair point
Aug 18 03:30:09 <kremlin> but!
Aug 18 03:30:32 <kremlin> research unix 6 -> bsd -> macOS
Aug 18 03:30:37 <kremlin> i still consider unix
Aug 18 03:30:39 <zmatt> osx
Aug 18 03:30:43 <zmatt> not MacOS
Aug 18 03:30:55 <zmatt> classic MacOS has absolutely nothing remotely to do with unix
Aug 18 03:31:14 <kremlin> all from scratch?
Aug 18 03:31:30 <zmatt> originally in 68k assembler and Pascal
Aug 18 03:31:39 <kremlin> neither was win32, but i still consider it basically unix. it doesn't depart wildly from unix's model
Aug 18 03:31:43 <Rickta59> * wonders what happen to my phonebook mac developer guide
Aug 18 03:31:55 <Rickta59> macos?
Aug 18 03:31:57 <Rickta59> unix?
Aug 18 03:32:00 <Rickta59> hardly
Aug 18 03:32:05 <zmatt> kremlin: http://www.pagetable.com/?p=50 download volume i, read it
Aug 18 03:32:08 <zmatt> or browse it
Aug 18 03:32:10 <kremlin> also you were right -- no TDA19988 documentation freely available. i asked nxp for them, though
Aug 18 03:32:23 <Rickta59> inside mac right
Aug 18 03:32:40 <zmatt> actually do read the human interface guidelines
Aug 18 03:32:56 <zmatt> it's amazing how many details they got right then that people still continually fuck up today
Aug 18 03:33:09 <Rickta59> sadly that started the years of hungarian programming notation
Aug 18 03:35:04 <zmatt> funny, I don't see it in the example program in chapter 1
Aug 18 03:37:39 <Rickta59> i must be misremebering and confusing with windows
Aug 18 03:37:46 <zmatt> :)
Aug 18 03:37:56 <zmatt> windows is hungarian notation hell indeed
Aug 18 03:40:05 <Rickta59> i used to remember getting boxes and boxes of docs and new code from the apple developer program
Aug 18 03:42:11 <zmatt> kremlin: does openbsd have /dev/mem ?  since I have a utility that dumps and to some degree validates lcdc config if you want
Aug 18 03:42:35 <kremlin> zmatt: we do! (sort of)
Aug 18 03:43:04 <kremlin> you can only interact with /dev/mem before system securelevel raises (happens right before /etc/rc runs)
Aug 18 03:43:15 <kremlin> don't worry about that though, "yes" is the answer to your question :)
Aug 18 03:43:17 <kremlin> i'd love that script
Aug 18 04:00:48 <zmatt> see pm
Aug 18 07:22:11 <lord_> hi everyone. i am doing multiple camera interfacing with bbb. my one camera is not working properly. i have also tested it alone(single camera) with bbb but still it shows the same result. it captures the image and also generates output file but the image file is complete black.what should i do to resolve this issue. kindly help..
Aug 18 07:36:00 <Defiant> lord_: can you reproduce this on a linux pc?
Aug 18 07:57:55 <lord_> Defiant: no it is not working through code even on linux pc. yess but it is capturing perfectly fro mmy cheese webcam booth
Aug 18 07:58:38 <Defiant> lord_: if you get the same problem on your linux pc then it is obviously not beagle related. Probably a driver problem.
Aug 18 07:59:17 <lord_> ohk.. let me check this again
Aug 18 08:19:28 <lord_> Defiant: if you are talking about the issue of webcam driver. then dont you think that if there would be any driver problem then it should not capture anything. it is capturing 1.8kb image.
Aug 18 08:22:37 <Defiant> lord_: Thats just a wild guess. Could also be webcam related. I don't know your application, maybe you should try to capture a stream, you might notice that the webcams first frame is always black and then gets brighter
Aug 18 08:25:25 <lord_> hm. at just want my camera to cmapture a single image
Aug 18 08:25:32 <lord_> at this time *
Aug 18 08:35:46 <zmatt> lord_: disable usb autosuspend
Aug 18 08:35:55 <zmatt> lot of cams behave badly
Aug 18 08:36:49 <zmatt> append   usbcore.autosuspend=-1    to the cmdline variable set in /boot/uEnv.txt
Aug 18 08:36:53 <zmatt> and reboot
Aug 18 08:36:58 <zmatt> cam shall work
Aug 18 08:37:00 <zmatt> :)
Aug 18 08:38:13 <zmatt> (hopefully)
Aug 18 08:39:24 <zmatt> I'm not really sure why this happens on BBB but not desktops though, my impression was that linux disables autosuspend unless it explicitly knows it to be safe for a device

Aug 18 20:01:57 <JakeGier> I think I have a video problem with my beaglebone black
Aug 18 20:07:27 <dlech> Anyone up to snuff on the latest PRU sdk?
Aug 18 20:07:31 <dlech> I'm following http://processors.wiki.ti.com/index.php/PRU_Training:_Hands-on_Labs
Aug 18 20:07:43 <dlech> doing lab 5, but it is not working quite right
Aug 18 20:08:11 <dlech> it all looks good up to the point where it is supposed to register a rpmsg device
Aug 18 20:09:50 <dlech> There is nothing in /sys/bus/rpmsg/devices/ so there is nothing for the rpmsg_client_sample driver to bind to
Aug 18 20:11:00 <dlech> no errors in dmesg: http://paste.ubuntu.com/23068353/
Aug 18 20:12:07 <dlech> I'm using pru-icss-4.0.2 from ti-processor-sdk-linux-am335x-evm-03.00.00.04
Aug 18 20:12:44 <dlech> and 4.4.16-ti-rt-r38 kernel from github.com/beaglebone/linux
Aug 18 20:16:39 <dinuxbg> dlech: Which version of pru-software-support-package are you using?
Aug 18 20:17:07 * dlech looking...
Aug 18 20:17:40 <dlech> dinuxbg, 2.1.2
Aug 18 20:18:09 <dlech> installed via ccs6
Aug 18 20:19:50 <dinuxbg> dlech: Where did you get the examples from? I think you should use version 4, because version 5 has incompatible changes to virtio signalling.
Aug 18 20:20:45 <dlech> dinuxbg, the examples are from ti-processor-sdk-linux-am335x-evm-03.00.00.04/example-applications/pru-icss-4.0.2/labs/lab_5
Aug 18 20:21:10 <dlech> so I assume I am using version 4?
Aug 18 20:21:26 <dinuxbg> yes, you seem to be running a correct version.
Aug 18 20:23:16 <dlech> I'm not using the kernel from ti-processor-sdk-linux-am335x-evm-03.00.00.04 though
Aug 18 20:23:52 <dinuxbg> dlech: that might be the reason.
Aug 18 20:24:14 <dinuxbg> try updating your examples to version 5 from here: https://git.ti.com/pru-software-support-package
Aug 18 20:25:24 <dinuxbg> There is incompatible change in virtio between version 4 and 5.
Aug 18 20:26:27 <dlech> dinuxbg, thanks I'll check it out later today.
Aug 19 02:14:21 <dlech> dinuxbg, I tried v5 and it worked! Thank you very much for your advice. :-)
Aug 19 02:15:02 <dlech> Is there a mailing list or something I can subscribe to in order to keep on top of breaking changes?
